Is there a way to create a recurring function in R to sample 35 sets of 2-digit random numbers

Question

I am currently learning R programming, and I was tasked to generate a set of 20 two-digit random numbers. I know that I can paste sample(0:9, 2, replace=TRUE) in 20 lines, but I was wondering if there's a way to make a recurring function (like in Python) so that the code will be shorter. I searched how to create recurring functions in R, but I can't figure out how to count the generated numbers so that I can assign an if statement to terminate it. I would very much appreciate any help. Thank you!

You can use -

set.seed(2301)
sprintf('%02i', sample(99, 20))
#[1] "52" "93" "27" "01" "80" "37" "16" "83" "46" "32" "39" "57" "59" 
#    "26" "89" "75" "17" "70" "12" "90"

Or with two samples

set.seed(1422)
paste(sample(0:9, 20, replace = TRUE), sample(0:9, 20, replace = TRUE), sep = '')
#[1] "88" "71" "36" "01" "31" "92" "72" "61" "72" "39" "21" "03" "39" 
#    "74" "68" "87" "95" "92" "16" "34"
